When I bought my Percs they were very young (about 1/4 inch). I thought they were false percs at the time because they were mostly orange and white with thin black outline on the white bands. Now 6 months later they have grown considerably [2 inches now] and have developed the colors that are witnessed on the true percs (more dark orange/black areas, thicker bands of black). Is this normal that very juvinile clown fish are harder to distinguish?
